SEE ALSO THE C TEST AND THE CAPACITOR TESTING SECTION OF
THIS CHAPTER.
The CS and CP tests can be used to measure the capacitance of a wide
range of components up to 1 milli-farad.
Test Conditions
To measure capacitance, the tester applies an AC voltage across the
designated terminals. It then measures the voltage and the resulting current.
Dividing the voltage by the current gives the complex impedance, from which
the capacitance is extracted using harmonic analyses.
Choosing the Test Signal
Recommended test conditions for different values of capacitance are the same
as for the C test.
